2112 was on the Gibson.com list & it was fun to see people complain that it's not a concept album because only one side was "concept". I'd probably have it in my top 20.

A lot of others complaints about the Gibson list related to Sgt. Pepper being in there. A lot of folks saying that it's not a concept album, that just because it might be connected musically doesn't make it a "concept" album. Who knows?! But it sure is fun to discuss & bitch about.
